Keeping the date at the table

  • Write the date down at the end of every session. Travel days, a long rest in town and two weeks of downtime all count, so add them up before you write it.
  • Put the date at the top of each recap so your players can plan around it.
  • Give your threats a date. When the date passes, something happens whether the party was there or not.

Let SCRY keep the date

SCRY records your game on Discord and writes the session notes. Your campaign gets this calendar too, and the dates that come up at the table land on its timeline without you counting days by hand.
